Someone asked me recently if I knew how to fix door windows that are hard to roll up and down. My answer was “yes” and “no”. “Yes”, I thought I knew how to fix them; “no” because I tried it once before and made them worse! The timing of the question was perfect because I was having trouble with my own power windows running very s-l-o-w-l-y as a result of the last time I tried to fix them.
